Circuit Description
The switch that failed and generated this diagnostic trouble code (DTC) is part of the DDM or the PDM. When a switch is activated, the DDM/PDM then either actuates the appropriate component or sends a message over the serial data link to the appropriate module to actuate the appropriate component.
Conditions for Running the DTC
| • | System voltage is between 9.0 and 16 volts. |
| • | Ignition switch is in the ON position. |
Conditions for Setting the DTC
If the DDM or the PDM receives multiple inputs from a single switch at the same time for more then 160 milliseconds, the DDM/PDM sets the DTC. The following switches will set this DTC:
| • | The door lock switch |
| • | The power window switch |
| • | The window lockout switch |
Action Taken When the DTC Sets
The DDM/PDM ignores the continuous inputs from the switch. The DDM/PDM will not respond to the invalid inputs as a command for the component. The DDM/PDM will respond to all other valid switch inputs.
Conditions for Clearing the DTC
When the switch input status changes, the DDM/PDM clears this current DTC and stores the DTC as a history DTC. The history DTC will clear either after 50 ignition switch cycles without a repeated failure or in response to a scan tool command.

1 | Did you perform the Door Systems Diagnostic System Check? | Go to Step 2 | |
2 |
Does the scan tool display an inactive state? | Go to Step 3 | Go to Step 4 |
3 |
Does the switch parameter change state? | Go to Testing for Intermittent Conditions and Poor Connections in Wiring Systems | Go to Step 4 |
4 | Inspect for poor connections/terminal tension at the door module harness connector. Refer to Testing for Intermittent Conditions and Poor Connections and Connector Repairs in Wiring Systems. Did you find and correct the condition? | Go to Step 6 | Go to Step 5 |
5 |
Important: Perform the set up procedure for the appropriate door module. Refer to Service Programming System (SPS) in Programming. Replace the appropriate door module. Refer to Door Lock and Side Window Switch Replacement - Driver Side or Door Lock and Side Window Switch Replacement - Passenger Side . Did you complete the replacement? | Go to Step 6 | -- |
